Physician Schedule

From April 2026, our clinic will operate under a new management structure.
With the addition of Dr. Matsuda, two doctors will be on duty at Kojimachi Clinic on selected weekdays.
For more details, please see “Changes to Clinic Management from April 2026.”

All our doctors speak English, although they are not native speakers, so their proficiency varies. Please note that some of our staff, including nurses and medical clerks, do not speak much English, so you may be assisted with translation software.

Attending doctor at Kojimachi

* Dr. Iwahashi, the former Medical Director, will continue to provide consultations until the end of May 2026.

* From June, only one doctor will be on duty on Sundays, which may result in longer wait times and limited appointment availability. We recommend visiting on a weekday whenever possible.
